Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

- Charging will start, the fan may come on automatically. The
status LEDs lights green while the rech. batt. is being charged.
- Once the rech. batt. has been charged the instrument will
automatically change to trickle charge. The status LEDs
permanently light green.
5.2.1.3. Battery care
> Do not fully exhaust rechargeable batteries.
> Store rech. batts. only in charged condition and at low
temperatures, but not below 32 °F.
> For longer breaks you should discharge and recharge the
batteries every 3 months. Trickle charging should not exceed 2
days.
5.2.1.4. AC Power supply
In case of danger the instrument must be disconnected from the
electric power supply by simply pulling out the power cord.
> Always position the instrument so that the power supply plug
can be easily reached.

Control unit
1. Connect the plug of the power supply to the power supply
socket on the control unit.
2. Connect the plug of the power supply to an electiric socket.
- The control unit is powered by the power supply.
- If the control unit is switched off the rech. batt. charging process
will start automatically. Switching the control unit on has the
effect of stopping battery charging and the control unit being
powered via the power supply.
Analyzer box via internal power supply
> Connect the power cord to analyzer box.
- The analyzer box is powered via the internal power supply.
- If the analyzer box is switched off the rech. batt. charging
process will start automatically. Battery charging stops when the
flue gas analyzer is switched on by the control unit.
Analyzer box via DC-voltage input DC
✓ Cable with battery terminals and adapter for connection to
analyzer box required (0554 1337, accessory).
- If the analyzer box is switched off the rech. batt. charging
process will start automatically. Battery charging stops when the
flue gas analyzer is switched on by the control unit.
5.2.2. Connecting probes
Probe detection takes place during the activation
process: Probes that are required must always be
connected before the analyzer is switched on, or the
analyzer must be switched off and then on again after a
probe change, so that the correct sensor data can be
shown.
> Connect the required probes to the corresponding ports.

(ascending or descending flank) measuring programs.
> Activating the trigger input, with external voltage supply
(5...12 V):
> Activating the trigger input, with supply via instrument voltage
(12 V):
When using the instrument voltage the analyzer can only
be started via the trigger input from the switched off state
when the AC power cord is plugged in.
5.2.4. Connecting system components
5.2.4.1. Connection using contact strip
The control unit can be plugged onto the analyzer box.
1. Place the guide groove in the bottom side of the control unit

unit, only the measurement data from one analyzer box can
be displayed at a time, or only one analyzer box can be
activated respectively. This is accomplished by selecting
the analyzer box, see
Measure values of diluted sensors (with enabled
measurement range extension) underlined on the print
Search for analyzer boxes, page 42.
If several analyzer boxes are connected to a notebook/PC,
the analyzer boxers can be activated and opened parallel
to each other, i.e. to display measuring channels of
different analyzer boxes parallel to one another.
If a notebook/PC or data bus controller (0554 0087) has
several connected and enabled measuring boxes, the
minimum measuring rate changes, depending on the
number of measuring boxes, as follows:
Measuring
boxes
Minimum
measuring rate
1 to 2 1 sec
3 to 4 2 sec
5 to 8 3 sec
9 to 16 5 sec
> Connect the data bus cable to the data bus interfaces.
Please observe the following points when setting up a connection
via data bus cable:
• Use only testo data bus cables
• Do not route data bus cables in the vicinity of electric power
cables.
• Ensure sufficient power supply by supplying each analyzer box
with AC voltage.
• The cables should ideally be plugged in before the system is
switched on. Connecting during operation (hot plugging) is
possible, however, depending on the combination the system
may need to be switched off and on again.
• The connection cannot be separated under load.
• Data bus subscribers: max. 16 analyzer boxes in one data bus
system.

• Cable length: max. 164 ft. between control unit and analyzer
box, max. 2,624 ft. between all analyzer boxes in the data bus
system.
• The bus system must have a defined electrical termination, see
below.
Electrical termination of the bus system
The data bus system is linear in structure. The control unit or the
testo data bus controller with USB connection represents the
beginning of the line.
The end is represented by the last components connected in the
system (analyzer box or analog output box). This component must
have a defined electrical termination.
An analog output box is the furthest subscriber.
> Plug the data bus termination plug into the data bus socket on

rate is calculated from the geometries entered
here together with the measured velocity.
Pitot Tube
Factor
The parameter "Pitot tube factor" influences the
measurement of flow speed, volume flow rate
and mass flow. The Pitot factor depends on the
type of Pitot tube used:
Straight Pitot tubes: Factor = 0.67
Prandt’l Pitot tubes (bent): Factor = 1
Humidity The parameter "Humidity" (combustion air
humidity) influences the calculation of qA (flue
gas loss) and flue gas dew point. The factory
setting is 80.0% humidity. To achieve a higher
accuracy, the values can be adjusted to the
actual ambient conditions.

Parameter Description
Barometric
pressure
The input of the barometric pressure and
the height above sea level is only
required when no absolute pressure is
available (no CO2 IR module present).
The barometric pressure influences the
calculation of flow speed, volume flow, mass flow
and flue gas dew point. To achieve a higher
accuracy, the values can be adjusted to the
actual ambient conditions.
This is 1013mbar (14.6 psi) as an annual
average, regardless of the altitude. Depending on
the current weather, this pressure can fluctuate
by ±20mbar (8 "H2O) around the annual average.
Altitude The height above sea level influences the
calculation of flow speed, volume flow, mass flow
and flue gas dew point. To achieve a higher
accuracy, the value can be adjusted to the actual
ambient conditions.
Dewpoint The parameter "Dewpoint" (combustion air
dewpoint) influences the calculation of qA (flue
gas loss) and flue gas dew point. The factory

6.1.2.1. Dilution
(only available via tab Analyzer Box and with the measurement
range extension option)
Option dilution (for single slot with selectable dilution factors
With active dilution the measuring gas for the sensor in slot 6 is
diluted with ambient air (other possibility: nitrogen gas) in a
controlled manner. For this purpose, the diluting gas is drawn
through a separate gas inlet by a pump and a valve operating on
the principle of pulse width modulation. A filter is installed to protect
the gas path against dust.
If the dilution system is active this is indicated by a clearly
noticeable clicking of the valve. In addition the symbol 1/x appears
at the right hand top of the display (in the header) and the selected
dilution factor appears at the corresponding parameter (the
complete line of the diluted parameter appears against a blue
background).
The following dilution factors can be manually set:
www. .com information@itm.com1.800.561.8187Downloaded from www.Manualslib.com manuals search engine

Factor Ratio of diluting gas: Measuring gas
x 1 no dilution
x 2 1 : 1
x 5 4 : 1
x 10 9 : 1
x 20 19 : 1
x 40 39 : 1
Auto dilution 4 : 1
If the dilution stage auto-dilution is selected, dilution (5x) is
activated automatically when the set switch-off threshold of the
sensor in slot 6 is reached.
• If the surrounding air contains interfering gases, push
the hose onto the dilution inlet and place in a clean
atmosphere.
• If gas from a gas cylinder is used, observe a max.
pressure of 12 "H2O (30hPa)
• Diluting also changes the resolution of the reading
display, i.e.:
Undiluted resolution 1ppm, with factor 10 resolution
10ppm.

6.1.4.2. CxHy-Sensor
The CxHy-Sensor can be activated/deactivated.
The HC-Sensor menu under Sensor settings is only
displayed if an HC sensor is connected.
This sensor is a Pellistor which always requires a certain amount of
O2 to operate (approx. 2% O2). This sensor would be destroyed at
lower values. The sensor therefore switches off at inadequate O2
values. If it is known from the beginning that values below 2% do
exist, the sensor can also be switched off manually. CxHy-Sensor
On starts the flue gas analyzer with a zeroing phase (30s).
For proper functioning the sensor is heated up to approx.
500°C, duration: approx. 10min. This means that the
sensor needs to be zeroed again 10min after the device
has been switched on, in order to prevent drifting (into the
"minus" range).

The sensor protection is activated if the threshold is exceeded, the
measuring gas is diluted. If the threshold is exceeded again, the
system will be shut down.
To deactivate sensor protection the thresholds must be set to
0ppm.

6.1.4.4. Calibration/adjustment
CO-, SO2-, NO2-, NO-, O2- and CO2-(IR)-sensors can be tested
(calibrated) and adjusted.
The calibration of the O2- sensor (O2 reference) generally takes
place in the same way as the calibration of the toxic sensors. The
entered nominal O2-value is only temporary, i.e. the nominal value
will be overwritten the device is switched off and on again the next
time or in case of zeroing. The same applies when a measuring
program passes through a zeroing phase. The O2 test gas must
also be applied to the measuring gas input (as with the toxic
sensors).
If obviously unrealistic readings are displayed, the sensors
should be checked (calibrated) and, if required, adjusted.
Have the calibration/adjustment carried out by qualified
personnel.
To ensure that specific accuracies are retained, testo
recommends testing every six months and recalibration
when required, except when required by local or state
regulations.
www. .com information@itm.com1.800.561.8187Downloaded from www.Manualslib.com manuals search engine
62. 62
Adjustments made with low gas concentrations can lead to
accuracy deviations in the upper measuring ranges.
The sensor protection (shut-down function) is not
deactivated. The test gas concentration should therefore be
lower than the set thresholds for the sensor protection.
The function of to dilute all (x5) is automatically
deactivated.
If the instrument is fitted with an CxHy sensor, it should be
switched off before test gas is applied.
If a CxHy-Sensor is fitted, switch this off before measuring
test gases with O2 contents <2%. If you forget to do this,
the sensor will switch off automatically during the
measuring process, but will still be strained unnecessarily.
The following boundary conditions must be met when calibrating /
adjusting:
• Use absorption-free hose material.
• Select Test Gas as fuel
• Switch on the flue gas analyzer at least 20 minutes before
calibration/adjustment (to warm up)
• Use clean air for gas zeroing
• Maximum overpressure of the test gas 12.04 "H2O
(recommended: pressureless via bypass)
• Apply the test gas for at least 3 minutes
Recommended test gas concentrations and compositions can be
found in the Test Gas Manual (Order-No. 0981 2313) or in the
Download Center.

6.2. Measuring
6.2.1. Preparing for measurement
The combustion air temperature is continuously measured
by the temperature sensor installed in the analyzer box.
The fresh air required for the zeroing phase is drawn in
through the exhaust if no fresh air valve (option) is installed
and through the valve inlet if a fresh air valve is installed.
The flue gas probe can thus already be inside the flue gas
channel before or during the zeroing phase.
The testo 350 can be operated as follows:
• lying down
• hanging horizontally down by its handle
• plugged vertically to the wall bracket by the handle
To prevent measuring errors the position of the testo 350
must not be changed during a measurement.
Under ambient temperatures of 50° F the CO2-(IR) sensor
requires a shorter heat-up time to reach full measuring
accuracy. At 23 °F this typically is 15 min.

69. 69
Before switching on
> Check whether:
• All system components are properly connected.
• All required probes / sensors are connected.
• The power supply of all system components is guaranteed.
During then zeroing phase
During the zeroing phase the sensors of the analyzer are zeroed.
Zero point and drift of the sensors are checked. The O2 value is set
to 21% O2.
> Make sure that the ambient air is free of interfering gases (i.e.
CO, NO) during the zeroing phase!
Before the measurement
> Set the fuel for the combustion system to be measured.
> Assign the required measurement parameters and units to a
display field in the measurement view.
> Activate the measurement site to which the readings are to be
assigned.
> Make sure that the gas outlets are free, so that the gas can
escape without obstruction. Otherwise the measurement results
may be corrupted.
Measurements with the CxHy sensor
WARNING
Dangerous mixture of gases
Danger of explosions.
> Perform measurements only in flue gas ducts.
> Only measure gases which do not form a combustible mixture
in the ambient air.
There must always be sufficient oxygen in the flue gas to
prevent the CxHy sensor from being destroyed. With an
O2 content of less than 2% the CxHy sensor switches off
automatically (protective function). Higher concentrations of
silicones, H2S and sulphurous hydrocarbons can also lead
to the destruction of the CxHy sensor.
Zeroing takes place automatically when the CxHy sensor is
activated. To ensure that accurate CxHy readings are obtained,
www. .com information@itm.com1.800.561.8187Downloaded from www.Manualslib.com manuals search engine
70. 70
you should then wait about 10 min. (with the analyzer switched on)
before starting another zeroing process manually.
To prevent the CxHy sensor from drifting during lengthy
measurement operations, zeroing should be carried out from time
to time.
6.2.2. Using the flue gas probe
Checking the thermocouple
> Make sure that the thermocouple of the flue gas probe does not
touch the probe basket. Bend the thermocouple back if
necessary.
Aligning the flue gas probe
> Turn the probe to align the thermocouple so that it is freely
exposed to the flue gas flow.
> Align the flue gas probe in the flue gas duct so that the tip is in
the hot spot (area of the highest flue gas temperature).
6.2.3. Applications
You can choose from fixed saved and a user defined application
(application defined on the basis of the measuring object).
The memory contains suitable device settings for the analyzer box
and typical fuels and calculations for these applications. These
quickly provides you with optimized device configurations for the
respective measuring task and the device will automatically inform
you about important application specific peculiarities (information in
the display).

6.2.3.1. Flue Gas, Flue Gas + m/s, Flue Gas + Δp, Program for all
analyzer boxes, Exhaust Gas before + after catalyst
The flue gas menus (Measurement Type) are the central
measuring menus, which – in addition to the readings measured
with this function – contain the readings of all measurements
performed (if selected in the menu Measurement view). All
readings can also be saved in or printed out from these menus.
The flue gas menus can always be selected, irrespective of the
plugged in sensors.
Measuring functions of the flue gas menu:
• The measurement type Flue Gas can be used to perform a flue
gas measurement.
• The measurement type Program for all analyzer boxes can
be used for i.e. a bus system, in which several flue gas
analyzers are interconnected. A measuring program can
thereby be defined and transferred to all analyzer boxes.
• The measurement type Exhaust Gas before + after cat
enables synchronous measuring of exhaust gas concentration
before and after the catalyst. For this flue gas menu two
measuring boxes are required, which are linked via the testo
data bus. The readings of both analyzer boxes are displayed
parallel in the display of the control unit to provide a quick
overview over the condition of the catalyst.
• With measurement type Flue Gas + m/s a flue gas
measurement can be performed in parallel to a flow
measurement (+ volume / mass flow calculation) via a Pitot tube
(the connecting cable for the thermocouple of the straight Pitot
tube must thereby not be connected to the sensor socket of the
instrument).
• The measurement type Flue Gas + ∆P can be used to perform
a flue gas measurement with parallel differential pressure
measurement.
After measurements with high concentrations and after
longer measurements the instrument should be rinsed with
fresh air, so that the sensors can be regenerated again.
